Bottlenose question
Hi, this is my first post and it's worth mentioning that i don't have a magnet yet so i dont yet have a 'feel' for how an implant works. but i was wondering if EM fields picked up by implants interfere with signals sent by a bottlenose? for example if you were to take the rangefinder example used in the wiki, and used this while walking around an EM field source like a microwave, would the rangefinders output be distorted?

Some people say you can feel the difference between fields kicked of by electronics.
It isn't perfect and the makers will be the first to tell you.
I don't see interference with the device but rather the magnet.
Hope that helps and welcome to the club! Don't hesitate to post questions it helps you and gives people like me the chance to talk and sometimes make a fool of myself ;)
With the glued on magnets, I have felt the buzz of some power adapters and could easily feel the push or pull of permanent magnets while moving my hand over them. I have yet to feel anything from a microwave oven and the only power cord I could feel anything around was an air conditioner using a lot of power. Again, a real implant should be more sensitive but I still think the coil from the bottlenose would be stronger than most interfering magnetic fields considering the coil of the device would be closer to the magnet than the interfering field.
I haven't tried a bottlenose but have started ordering parts to possibly build my own. I couldn't locate actual plans for the bottlenose but I assume it is basically an Arduino microprocessor controlling an ultrasonic ping sensor with the output going to a coil instead of a display. The programming could be customized however you want. It sounds like a fun and potentially useful device.
Keep in mind, the implanted magnet is just one way to get the information from the sensor into your body. Light, sound, vibration, etc. could be used instead of the magnetic implant.
Here's a video that shows a device something like a bottlenose.

https://github.com/GrindhouseWetware/bottlenose Slight mistake with the diagram, it;s supposed to be an inductor there and not a capacitor, Been meaning to make that fix. That's also just for the bluetooth based example. The standard sensor-to-pulse assembly essentially puts an inductor where you'd expect an LED to go. For most LED based feedback examples. But here's the current arduino library! We also have code in there for bluetooth communications over android as well.
My plan, to start with, is just to use the Ping example and add in an output to an LED or coil flashing that output somehow to indicate the distance. Once I got that part working, I can make things more fancy.
I am still waiting for the Ping sensors to be delivered but I got the bottlenose files to verify and upload to the Arduino.
I found the solution here.
What I had to do was move the bottlenose.cpp , bottlenose.h , and keyword.txt files out of the Bottlenose folder and into the main bottlenose-master folder.
I don't know if this is/was a problem just for me or if others would have the same problem with the https://github.com/GrindhouseWetware/bottlenose files.

This is closer to what I was thinking without all the extra code since I don't have an android phone anymore.
There is a file included called "sleep.ino" which sounds very interesting to me but I don't understand how the potentiometer is hooked up to read rapid eye movements.
It sounds like this could be adapted into some kind of sleep mask that would flash an LED or something to alert the sleeping person that they were in REM sleep and possibly induce lucid dreaming.
